I was just wondering if someone on here could give me some advice about mixing? The cans I am using are female tip cans so mixing has to be done with one can on top of the other. I am confused about which can goes on the top and bottom. The can you are mixing into is on the bottom and the can you are getting paint from is on the top right? Also,which can has to be warm and which one has to be cold? I assume the top can has to be warm and the bottom can has to be cold. Is that correct. Any advice would be much appreciated. Thanks!
